Summary
Men with chronic prostatitis experience elevated seminal oxidative stress, indicated by higher reactive oxygen species (ROS) and lower total antioxidant capacity (TAC). This oxidative stress may contribute to male infertility concerns.
Area of Science:
- Urology
- Reproductive Medicine
- Biochemistry
Background:
- Prostatitis is suspected to impact male fertility, but the underlying mechanisms remain unclear.
- Granulocytes in prostatic fluid associated with prostatitis generate reactive oxygen species (ROS), which can harm sperm function.
- This study investigates the role of oxidative stress in chronic prostatitis and its potential link to male infertility.
Purpose of the Study:
- To compare levels of reactive oxygen species (ROS) and total antioxidant capacity (TAC) in men with chronic prostatitis versus healthy controls.
- To evaluate a novel oxidative stress index (ROS-TAC score) in these groups.
- To explore the relationship between prostatitis, oxidative stress, and male infertility.
Main Methods:
- Semen specimens were analyzed from 36 men with chronic prostatitis, 8 with prostatodynia, and 19 controls.
- Leukocytospermia was assessed using the Endtz test (myeloperoxidase assay).
- ROS and TAC levels were measured via chemiluminescence assay, and a composite ROS-TAC score was calculated.
Main Results:
- No significant differences in sperm concentration, motility, or morphology were observed between groups.
- Patients with chronic prostatitis exhibited significantly higher ROS levels and lower TAC compared to controls.
- The ROS-TAC score was significantly lower in patients with chronic prostatitis, indicating higher oxidative stress, regardless of leukocytospermia status.
Conclusions:
- Men with chronic prostatitis or prostatodynia demonstrate seminal oxidative stress.
- This oxidative stress is present irrespective of leukocytospermia.
- These findings may help clarify the association between prostatitis and male infertility.
